This application is a continuation of U.S. patent application Ser. No. 16/508,219 filed Jul. 10, 2019, the contents of which is incorporated herein by reference in its entirety.

BACKGROUND 1. Technical Field

The present disclosure relates to a semiconductor device and a method of manufacturing the same, and, more particularly, to a semiconductor device including an antenna zone.

2. Description of the Related Art

There is a continuing demand to reduce dimensions of semiconductor devices. Miniaturization has had a severe impact on the design of a semiconductor device; in particular, on a wireless communication device, such as an RF (radio frequency) module. As an RF module is developing towards high-frequency applications (such as 5G applications), the antenna zone thereof should be thicker so that it can have sufficient power to transmit within a certain distance. Nevertheless, a thicker antenna zone cannot satisfy the miniaturization demand.

In addition, miniaturization also has had a severe impact on the assembly stresses generated during production of a semiconductor device; in particular, when the semiconductor device includes multiple metal interconnection structures. Such stresses may cause warpage of the semiconductor device or even detachment of a chip die thereof, resulting in a poor electrical connection between the chip die and the metal interconnection structures.

Therefore, it would be desirable to provide a semiconductor device with an improved antenna structure to reduce the assembly stresses generated thereof and prevent a poor electrical connection between the chip and the metal interconnection structures without compromising the miniaturization and high frequency demands.

DETAILED DESCRIPTION

Spatial descriptions, such as “above,” “top,” and “bottom” and so forth, are indicated with respect to the orientation shown in the figures unless otherwise specified. It should be understood that the spatial descriptions used herein are for purposes of illustration only, and that practical implementations of the structures described herein can be spatially arranged in any orientation or manner, provided that the merits of embodiments of this disclosure are not deviated by such arrangement.

The present disclosure provides for an improved semiconductor device with improved antenna structure that can reduce warpage of the semiconductor device and can satisfy miniaturization and high frequency demands.

FIG. 1 illustrates a cross-sectional view of a semiconductor device 100 according to an embodiment of the present disclosure. The semiconductor device 100 of FIG. 1 includes an antenna zone 102 and a routing zone 103.

The antenna zone 102 may be applied to a semiconductor device that may be operated at a high frequency. In some embodiments, the antenna zone 102 may be applied to a semiconductor device that may be operated at a frequency in the range of about 2 GHz to about 300 GHz, about 5 GHz to about 300 GHz, about 10 GHz to about 300 GHz, about 15 GHz to about 300 GHz, about 20 GHz to about 300 GHz, about 25 GHz to about 300 GHz, about 30 GHz to about 300 GHz, about 35 GHz to about 300 GHz, about 40 GHz to about 300 GHz, or about 45 GHz to about 300 GHz.

The antenna zone 102 includes a first insulation layer 101 and two or more second insulation layer 105, 120. The thickness and material of the first insulation layer 101 and the second insulation layer 105, 120 are determined depending on the desired function or property of the antenna zone 102. For example, if the antenna zone 102 is designed to be operated at a high frequency such as to be operated in the range of 30 GHz to 300 GHz, in order to reduce the transmission loss and to transmit for a long distance, the antenna zone 102 should be thicker and/or include materials with low dielectric constant and dielectric loss. Nevertheless, as the antenna zone 102 becomes thicker, it would become more costly and more difficult to process, such as when disposing a through hole therein or disposing a circuit thereon, which involves highly precise control and costly equipment. Moreover, the miniaturization demand may not be satisfied.

Therefore, in some embodiments, the first insulation layer 101 may have a thickness D1 of about 180 μm to about 600 μm, about 190 μm to about 600 μm, about 200 μm to about 600 μm, about 210 μm to about 600 μm, about 220 μm to about 600 μm, about 230 μm to about 600 μm, about 240 μm to about 600 μm, about 250 μm to about 600 μm, about 260 μm to about 600 μm, about 270 μm to about 600 μm, about 280 μm to about 600 μm, about 290 μm to about 600 μm, about 300 μm to about 600 μm, about 310 μm to about 600 μm, about 320 μm to about 600 μm, about 330 μm to about 600 μm, about 340 μm to about 600 μm, about 350 μm to about 600 μm, about 360 μm to about 600 μm, about 370 μm to about 600 μm, about 380 μm to about 600 μm, about 390 μm to about 600 μm, or about 400 μm to about 600 μm.

By forming the first insulation layer 101 with a thickness D1 within a specific range, the semiconductor device warpage can be reduced because a thicker insulation layer can provide more strength to reduce the stress caused by the comparative structural arrangement for an antenna, such as the comparative insulation layer and via arrangement, where the insulation layers have similar thickness and the vias are formed in the same direction.

The first insulation layer 101 has a first surface 101 a and a second surface 101 b opposite to the first surface 101 a.

The first insulation layer 101 includes one or more first conductive via 107 a, 107 b. The first conductive via 107 a, 107 b may be formed by mechanical drilling or by laser drilling. In some embodiments, the first conductive via 107 a, 107 b is a through hole formed by mechanical drilling and extending from the first surface 101 a of the first insulation layer 101 to the second surface 101 b of the first insulation layer 101 so that an electrical signal may be transmitted from one side of the first insulation layer 101 to the other side of the first insulation layer 101. Alternatively, the first conductive via 107 a, 107 b extends from the first surface 101 a of the first insulation layer 101 but ends before reaching the second surface 101 b of the first insulation layer 101.

One or more first connecting element 108 a, 108 b may be disposed adjacent to the first surface 101 a of the first insulation layer 101. In some embodiments, the first connecting element 108 a, 108 b electrically connects to the first conductive via 107 a, 107 b, respectively. The first connecting element 108 a, 108 b may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The first connecting element 108 a, 108 b may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.

One or more second connecting element 114 a, 114 b may be disposed adjacent to the second surface 101 b of the first insulation layer 101. In some embodiments, the second connecting element 114 a, 114 b electrically connects to the first conductive via 107 a, 107 b, respectively. The second connecting element 114 a, 114 b may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The second connecting element 114 a, 114 b may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.

One or more bonding bond and/or trace and one or more overlying interconnection structures therein 117 a, 117 b may be disposed on the first surface 101 a of the first insulation layer 101. The bonding bond and/or trace 117 a, 117 b may be a part of a circuit.

The first insulation layer 101 may include an insulation material or other suitable material that has low dielectric constant and/or low dielectric loss as a base material. In some embodiments, the first insulation layer 101 includes polypropylene.

The second insulation layer 105 is disposed adjacent to the second surface 101 b of the first insulation layer 101. The second insulation layer 105 has a second top surface 105 a, a second bottom surface 105 b opposite to the second top surface 105 a, and a second thickness D2. As shown in the embodiment of FIG. 1 , the second insulation layer 105 is disposed above the second surface 101 b of the first insulation layer 101.

The thickness D1 of the first insulation layer 101 is different from the thickness D2 of the second insulation layer 105. In some embodiments, the thickness D1 of the first insulation layer 101 is greater than the thickness D2 of the second insulation layer 105. By designing the first insulation layer 101 as having a thickness D1 greater than the thickness D2 of the second insulation layer 105 (or another insulation layer disposed above the second insulation layer 105), the warpage of a semiconductor device caused by a comparative antenna configuration can be eased because a thicker insulation layer can provide more strength to reduce the stress caused by the comparative antenna structural arrangement, such as the comparative insulation layer and via arrangement as described above. In some embodiments, the thickness D2 of the second insulation layer 105 may be in the range of about 70 μm to about 200 μm, about 75 μm to about 195 μm, about 80 μm to about 190 μm, about 85 μm to about 185 μm, about 90 μm to about 180 μm, about 95 μm to about 175 μm, about 100 μm to about 170 μm, about 105 μm to about 165 μm, about 110 μm to about 160 μm, about 115 μm to about 155 μm, about 120 μm to about 145 μm, or about 125 μm to about 140 μm.

The second insulation layer 105 defines one or more opening 119 a, 119 b. Each opening 119 a, 119 b corresponds to a respective second conductive via 111 a, 111 b. The opening 119 a, 119 b has a first width W1 close to the opening and a second width W2 close to the bottom. In some embodiments, the opening 119 a, 119 b inclines inwardly from the opening to the bottom. Therefore, the opening 119 a, 119 b has a first width W1 greater than a second width W2. Accordingly, the respective second conductive via 111 a, 111 b formed therein will also have a first width W1 greater than a second width W2 (e.g., the respective second conductive via 111 a, 111 b is formed by a shape inclining inwardly from the opening to the bottom). In some embodiments, the second conductive via 111 a, 111 b electrically connects to the second connecting element 114 a, 114 b.

One or more third connecting element 112 a, 112 b may be disposed adjacent to the second top surface 105 a of the second insulation layer 105. In some embodiments, the third connecting element 112 a, 112 b electrically connects to the second conductive via 111 a, 111 b. The third connecting element 112 a, 112 b may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The third connecting element 112 a, 112 b may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.

The second insulation layer 105 may include an insulation material or other suitable material that has low dielectric constant and/or low dielectric loss as a base material. In some embodiments, the second insulation layer 105 includes polypropylene.

The antenna zone 102 may include at least one first insulation layer 101 and at least one second insulation layer 105. In some embodiments, a number of the first insulation layers 101 and a number of the second insulation layers 105 are stacked together. In some embodiments, the first insulation layers 101 and the second insulation layers 105 are stacked in an alternative manner. In some embodiments, two or more first insulation layers 101 are stacked with single second insulation layer 105 in an alternative manner. In some embodiments, two or more second insulation layers 105 are stacked with single first insulation layer 101 in an alternative manner.

The routing zone 103 is disposed on the antenna zone 102. The routing zone 103 may be a RF routing zone. The routing zone 103 includes two or more third insulation layer 106, 113. In some embodiments, the third insulation layer 106, 113 is disposed adjacent the first insulation layer 101 and distant from the second insulation layer 105. The third insulation layer 106, 113 has a third top surface 106 a, 113 a, a third bottom surface 106 b, 113 b opposite to the third top surface 106 a, 113 b, respectively, and a third thickness D3.

The thickness D3 of the third insulation layer 106, 113 is different from the thickness D1 of the first insulation layer 101. In some embodiments, the thickness D3 of the third insulation layer 106, 113 is smaller than thickness D1 of the first insulation layer 101. By designing the third insulation layer 106, 113 as having a thickness D3 smaller than the thickness D1 of the first insulation layer 101, the warpage of a semiconductor device caused by a comparative antenna configuration can be eased because a thicker insulation layer is provided and a thicker insulation layer can provide more strength compared to a thinner one.

The thickness D3 of the third insulation layer 106, 113 may be substantially the same or different from the thickness D2 of the second insulation layer 105. In some embodiments, the thickness D3 of the third insulation layer 106, 113 is substantially the same with the thickness D2 of the second insulation layer 105. By forming the third insulation layer 106, 113 with a thickness D3 substantially equal to or corresponding to the thickness D2 of the second insulation layer 105, the third insulation layer 106 may substantially match the second insulation layer 105 through the first insulation layer 101 in thickness. Therefore, the semiconductor device warpage can be further eased because the antenna exhibits a more symmetry structure than a comparative one, which can reduce the stress caused by an asymmetry structure. In some embodiments, the thickness D3 of the third insulation layer 106, 113 may be in the range of about 70 μm to about 200 μm, about 75 μm to about 195 μm, about 80 μm to about 190 μm, about 85 μm to about 185 μm, about 90 μm to about 180 μm, about 95 μm to about 175 μm, about 100 μm to about 170 μm, about 105 μm to about 165 μm, of about 110 μm to about 160 μm, about 115 μm to about 155 μm, about 120 μm to about 145 μm, or about 125 μm to about 140 μm.

The third insulation layer 106 defines one or more openings 104 a, 104 b. Each opening 104 a, 104 b corresponds to a respective third conductive via 109 a, 109 b. The opening 104 a, 104 b, is defined by a shape and/or position substantially matching the opening 119 a, 119 b in the second insulation layer 105 through the first insulation layer 101 so that the third conductive via 109 a, 109 b formed in the opening 104 a, 104 b can substantially match the second conductive via 111 a, 111 b in shape and/or position through the first insulation layer 101. The opening 104 a, 104 b has a third width W3 close to the opening and a fourth width W4 close to the bottom. In some embodiments, the opening 104 a, 104 bb inclines inwardly from the opening to the bottom. Therefore, the opening 104 a, 104 b has a third width W3 greater than a fourth width W4. Accordingly, the respective third conductive via 109 a, 109 b will also have a third width W3 greater than a fourth width W4 (e.g., the respective third conductive via 109 a, 109 b is formed by a shape inclining inwardly from the opening to the bottom). In some embodiments, the third conductive via 109 a, 109 b electrically connects to the first connecting element 108 a, 108 b.

The third conductive via 109 a, 109 b may substantially match the second conductive via 111 a, 111 b in shape through the first insulation layer 101 (e.g., they both incline from outside to inside or incline inwardly from the opening to the bottom). The third conductive via 109 a, 109 b may also substantially match the second conductive via 111 a, 111 b in position through the first insulation layer 101. Unlike the comparative design of conductive vias which are all formed to incline from the same direction, this configuration of the third conductive via 109 a, 109 b and the second conductive via 111 a, 111 b of the present disclosure can ease the device warpage or detachment of a chip die from the device generated in a comparative via configuration by disposing a more substantially symmetry arrangement of the third and second conductive vias, for example, by disposing them in a substantially symmetry shape (e.g. as shown in FIG. 1 ) through the first insulation layer 101 or by disposing them at a more substantially symmetry position through the first insulation layer 101 or both.

A number of the second insulation layers 105 may be the same with or different from a number of the third insulation layers 106. In some embodiments, a number of the second insulation layers 105 may be the same with a number of the third insulation layers 106 to further improve the symmetry effect.

One or more fourth connecting element 110 a, 110 b, 118 a, 118 b may be disposed adjacent to the third top surface 106 a of the third insulation layer 106 of the routing zone 103. In some embodiments, the fourth connecting element 110 a, 110 b electrically connects to the third conductive via 109 a, 109 b. The fourth connecting element 110 a, 110 b may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The fourth connecting element 110 a, 110 b may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.

The third insulation layer 106 may include an insulation material or other suitable material that has low dielectric constant and/or low dielectric loss as a base material. In some embodiments, the third insulation layer 106 includes polypropylene.

FIG. 2 illustrates a cross-sectional view of a semiconductor device 200 according to an embodiment of the present disclosure. The semiconductor device 200 is similar to that illustrated in FIG. 1 , with a difference being that a fourth insulation layer 213 is disposed adjacent to the routing zone 103. In some embodiments, the fourth insulation layer 213 is disposed adjacent to the third top surface 113 a of the third insulation layer 113 and distant from the first insulation layer 101. In some embodiments, the second insulation layer 105 is disposed adjacent to the first insulation layer 101 and distant from the third insulation layer 106. In some embodiments, the second insulation layer 105 is disposed adjacent to the first insulation layer 101 and distant from the fourth insulation layer 213.

The fourth insulation layer 213 has a fourth top surface 213 a, a fourth bottom surface 213 b opposite to the fourth top surface 213 a, and a fourth thickness D4. As shown in the embodiment of FIG. 2 , the fourth insulation layer 213 is disposed on the third insulation layer 113.

The thickness D4 of the fourth insulation layer 213 is different from the thickness D3 of the third insulation layer 113. The thickness D4 of the fourth insulation layer 213 may also be different from the thickness D1 of the first insulation layer 101. In some embodiments, the thickness D4 of the fourth insulation layer 213 is smaller than the thickness D3 of the third insulation layer 113. In some embodiments, the thickness D4 of the fourth insulation layer 213 is smaller than the thickness D1 of the first insulation layer 101. In some embodiments, the thickness D4 of the fourth insulation layer 213 is smaller than the thickness D2 of the second insulation layer 105. In some embodiments, the thickness D4 of the fourth insulation layer 213 is smaller than the thickness D1 of the first insulation layer 101 and the thickness D3 of the third insulation layer 106.

By designing the third insulation layer 106, 113 as having a thickness D3 greater than the thickness D4 of the fourth insulation layer 213 (or another insulation layer disposed above the fourth insulation layer 213), the antenna device warpage in a comparative antenna configuration can be eased because a thicker insulation layer can provide more strength to reduce the stress caused by the comparative antenna arrangement of the insulation layers and vias compared to a thinner one. In some embodiments, the thickness D4 of the fourth insulation layer 213 may be in the range of about 30 μm to about 150 μm, about 30 μm to about 145 μm, about 30 μm to about 140 μm, about 30 μm to about 135 μm, about 30 μm to about 130 μm, about 30 μm to about 125 μm, about 30 μm to about 120 μm, about 30 μm to about 115 μm, about 30 μm to about 110 μm, about 30 μm to about 105 μm, or about 30 μm to about 100 μm.

The fourth insulation layer 213 defines one or more opening 218 a, 218 b. Each opening 218 a, 218 b corresponds to a respective fourth conductive via 215 a, 215 b. In some embodiments, the opening 218 a, 218 b inclines inwardly from the opening to the bottom. Accordingly, the respective fourth conductive via 215 a, 215 b will also be in a shape inclining inwardly from the opening to the bottom. The opening 218 a, 218 b is defined by a shape and/or position substantially corresponding to the opening 119 a, 119 b in the second insulation layer 105 through the first insulation layer 101 so that the fourth conductive via 215 a, 215 b formed in the opening 218 a, 218 b can substantially match the second conductive via 111 a, 111 b in shape and/or position through the first insulation layer 101. The opening 218 a, 218 b may also be defined by a shape and/or position substantially the same to the opening 104 a, 104 b in the third insulation layer 106 so that the fourth conductive via 215 a, 215 b can be substantially the same to the third conductive via 109 a, 109 b in the third insulation layer 106 in shape and/or position.

One or more fifth connecting element 216 a, 216 b may be disposed adjacent to the fourth top surface 213 a of the fourth insulation layer 213. In some embodiments, the fifth connecting element 216 a, 216 b electrically connects to the fourth conductive via 215 a, 215 b. The fifth connecting element 216 a, 216 b may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The fifth connecting element 216 a, 216 b may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.

The fourth insulation layer 213 may be a part of a stack of layers or a part of a routing zone each having substantially the same or different thickness. In some embodiments, the fourth insulation layer 213 is a part of a second routing zone or a part of a second RF routing zone.

FIG. 3 illustrates a cross-sectional view of a semiconductor device 300 according to an embodiment of the present disclosure. The semiconductor device 300 of FIG. 3 includes an antenna zone 302, a routing zone 303, a first protection layer 317, and a second protection layer 319.

The antenna zone 302 may be applied to a semiconductor device that may be operated at a high frequency. In some embodiments, the antenna zone 302 may be applied to a semiconductor device that may be operated at a frequency in the range of about 2 GHz to about 300 GHz, about 5 GHz to about 300 GHz, about 10 GHz to about 300 GHz, about 15 GHz to about 300 GHz, about 20 GHz to about 300 GHz, about 25 GHz to about 300 GHz, about 30 GHz to about 300 GHz, about 35 GHz to about 300 GHz, about 40 GHz to about 300 GHz, or about 45 GHz to about 300 GHz.

The antenna zone 302 includes a first insulation layer 301 and a second insulation layer 305. The thickness and material of the first insulation layer 301 and the second insulation layer 305 are determined depending on the desired function or property of the antenna zone 302. For example, if the antenna zone 302 is designed to be operated at a high frequency such as to be operated in the range of 30 GHz to 300 GHz, in order to reduce the transmission loss and to transmit for a long distance, the antenna zone 302 should be thicker and/or include materials with low dielectric constant and dielectric loss. Nevertheless, as the antenna zone 302 becomes thicker, it would become more costly and more difficult to process, such as when disposing a through hole therein or disposing a circuit thereon, which involves highly precise control and costly equipment. Moreover, the miniaturization demand may not be satisfied. The thickness of the first insulation layer 301 and that of the second insulation layer 305 may be substantially the same or different depending on the desired n function of the antenna zone 302.

In some embodiments, the first insulation layer 301 may have a thickness D5 of about 90 μm to about 300 μm, about 100 μm to about 290 μm, about 110 μm to about 280 μm, about 120 μm to about 270 μm, about 130 μm to about 260 μm, about 140 μm to about 250 μm, about 150 μm to about 240 μm, about 160 μm to about 230 μm, 170 μm to about 220 μm, or about 180 μm to about 210 μm.

One or more first connecting element 308 a, 308 b, 308 c may be disposed adjacent to the top surface of the first insulation layer 301 for electrical connection. The first connecting element 308 a, 308 b, 308 c may be a bonding bond and/or trace. A bonding pad may be, for example, a contact pad of a trace. The first connecting element 308 a, 308 b, 308 c may include, for example, one of, or a combination of, copper, gold, indium, tin, silver, palladium, osmium, iridium, ruthenium, titanium, magnesium, aluminum, cobalt, nickel, or zinc, or other metals or metal alloys.
